Salivary extracellular RNA (exRNA) and protein have been demonstrated to possess clinical utilities as biomarkers for early detection of oral and systemic diseases. More recently salivary exRNA were shown to be contained in exosomes, shuttling disease-specific exRNA from the disease organs via blood stream to salivary glands and into saliva as disease-specific salivary biomarkers.
